Ever wondered what the inside of an S50 looks like?

This weekend i'll mostly be stripping down the knackered motor !

Lets get started !

Cam cover off


Vanos unit off

Timing cover off

Cams out

First part of head off

Cylinder head off, looks good.

All the gubbins!

Top of block.


Lets hope I can recoup some cash on this little lot.

nice! bigpimpin, pleeease could you take some close up pics of down the inlet ports? would like to see their shape etc. any measurements (in particular diameter of each port - not at the surface but further in) would be greatly appreciated too. actually, pics etc of exhaust ports too would be cool.
so what's the plan from here then? you bought a new bottom end or whole engine? you selling on the old stuff?

[bigpimpin]

New engine arriving on Tuesday. Yes I'm selling off all the bits I can which should cover the cost of the original engine.

glad its coming along, I was gutted when your last one was foobarred!

S50 boys unite!

[bigpimpin]

Nope, standard issue E30 as far as I know.

what was the vanos unit like to get off??
did u use the bmw tools or some other method? i've got to change the head on one of these imminently and have been wonderin how u do it. the vanos unit is the only part i've had nothing to do with yet. the rest is just 6 pot bm isn't it? is lookin good in that touring tho.
even in bits

[bigpimpin]

The vanos just unbolts and pulls off, no BMW tools used, just my trusty digits!
